HAWSIEIR-SECURING DEVICE FOR SCOWS;

Specification of Letters Patent.

Patented Oct. 18, 191i).

Application filed February 25, 1910. Serial No. 545,851.

To all whom it may concern:

Be it known that I, GARRETT V. MITCHELL, a citizen of the United States, residing at Bayonne, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Hawser-Securing Devices for Sco'ws,'of which the following is a specification.

My invention relates to improvements in hawser securing devices for scows, particu larly for rotatable scows having interchangeable decks such as thatforming the subject of my co-pending application filed concurrently herewith.

It has for its object to provide a securing device for the purpose above set forth adapted to be secured to the fore end of a scow and having means'at each end adapted to be engaged by a hawser, whereby the hawser is adapted to be primarily held adjacent the uppermost deck of the scow and be disengaged therefrom, preparatory to the scow being rotated to discharge its load, allowing the hawser to drop by gravity and engage the lower means for its engagement, by which arrangement the hawser will al ways extend from thedeck which is uppermost.

It has for a further object to provide means for disengaging the hawser from the upper means for its engagement.

It has for a further object to provide means for operating the means for disengaging the hawser;

It has for a further object to provide means for guiding the hawser in its travel from the upper means for its engagement to the lower means therefor:

In the drawings illustrating my invention 1 of my securing devices removed. Fig. 4, a

side view thereof.

Referring to the drawings in which like reference characters designate correspond ing parts, I have illustrated the securing device forming the subject of this application, applied to a rotary scow 1, viz: that forming the subject of my co-pending application'above referred to, in order to give a clear understanding of its application'and operation, two of these securing devices bemg required on the fore end of the scow,

one adjacent each side, to secure the ends ofa bridle hawser thereto.

My hawser securing device which is constructed of metal, consists of straps 2 hav-' ing long arms 3 secured toopposite decks of the scow in alinement with each other, a short arm 4 at substantially right angles thereto and spaced from the end of the scow and an arched corner 5 provided with an inwardly opening recess 6 adapted to be engaged by a ring 7 of a hawser and a lug 8 extending into said recess from the short arm and being adapted to engage the outer circumference of the hawser ring and prevent it from accidentally slipping out of the recess, but permitting it to be easily and readily disengaged therefrom to allow it to fall by gravity into the recess of the lower strap preparatory to rotating the scow to discharge its load and interchange its decks so as to have-the hawser always extend from the deck of the scow which is uppermost.

The ends of the short arms 4 which are T shaped in transverse cross-section, are joined to the opposite ends of a T bar 9 by plates 10 are interchanged by reason of the rotation of the scow and the end of the hook 16 engages the inner circumference of the hawser ring when it is in the recess and when the bar is slid forward disengages the hawser ring from the lug S and moves it out of the upper recess, allowing it to fall by gravity into the recess of the other strap.

A lever 18 for sliding the bar 12 rests on top of said bar and'is provided at its rear end with forks 19, one having a journal 20 mounted in a bearing 21 in the rib 14: of the arm 3, and theother a journal 22 mounted in a bearing 23 in a plate 24:, bolted to the outer flange 13 and therear end of the slidable bar 12 is fulcrumed between the forks of the lever 18 on journal 26 mounted in bearings 27 in said forks forward of the fulcrum of the when the ends of the hawser securing device lever 18. By this arrangement of the lever .18 and the bar 12', when the lever is raised To prevent the lever 18 at the lower end of the hawser securin device from dropping down, it is secured just previous to the scowbeing rotated to dischar e its load, by means of arope 28, one end of which is permanently secured to the forward end of the .lever 18 and theother end tem orarily secured to the forward end of the ar 12.-

The operation is as follows: When it is desired to discharge the load from the scow,

the hawser is slightly slaekened and the lever 18 at the upper end of the securing device is pulled upward which causes the bar 12 to be slid backward and move its hook partially out of the depression 17 and as the end of its hook 16 is in enga ement with the hawser ring, said ring is isengaged from the lug 8 and moved out of the recess 6, thusallowing it to fall by gravity into the recess 6 in the strap at the lower end of the securing device, whereupon the scow is caused to rotate so-as to discharge its load, interchange its decks and the hawser will extend from the uppermost deck.

claim:

1. A hawser-securing device for rotatable scows, having reversible decks, said device having means adjacent each deck adapted to be engaged by the hawser, means adapted to positively support said hawser in elevated position, means adapted to guide the hawser from one to the other of said first mentioned means and means for positively disengaging the hawser from the first mentioned means, substantially as described.

2. A hawser securing device for rotatable .scows, having reversible decks, said device having means provided with recesses adapted to be engaged by the hawser, lugs adjacent the entrance to said recesses normally retaining said hawser therein, means adapted to guide the hawser from the recessjn one into the recess in the other of the first mentioned means and means for positively disengaging the hawser from the lugs and recesses, substantially as described.

, erases 3. A hawser securing devicefor rotatable scows, having reversible decks, said device having means provided with recesses adapted to be engaged by the hawser, lugs adjacent the entrance to said recesses normally retaining said hawser therein, means adapted to guide the hawser in its movement from the recess in one into the recess in the other of the first mentioned means, bars ada ted to be operated to disengage the hawser rom the lugs and recesses and levers adapted to operate said bars, substantially as described.

4. A hawser securing device for rotatable scows, having reversible decks, said device having means provided with recesses ada ted to be engaged by the hawser, lugs adjacent the entrance to said recesses normally retaining said hawser therein, means adapted to guide the hawser in its movement from the recess in one into the recess in the other of the first mentioned means, hooked bars adapted to be operated to disengage the hawser from the lugs and recesses, and meansadapted to operate said bars, substantially as described.

5. A hawser securing device for rotatable scows, having reversible decks, means provided with recesses adapted to by the hawser, means adapted to guide the hawser fron the recess in onefiiito' the recess in the other of the first mentioned means, bars adapted to be operated to disengage the hawser fromsaid recesses and fulcrumed.

levers, on which said bars are fulcrumed, adapted to operate said bars, substantially as described.

6. A hawser securing device for rotatable scows, having reversible decks, means pro vided with recesses adapted tobe engaged by the hawser, means adapted to guide the hawser in its movement from the recess in one into the recess in the other "of the first mentioned means, hooked bars adapted to be operated to disengage the hawser from said recesses and fulcrumed levers, on which said bars are fulcrumed, adapted to operate said bars, substantiallyas' described.

In testimony whereof I have signed my name in the witnesses.
